(OP)
When do you require wood connectors (i.e. Simpson products) to be galvanized?
On exterior applications only? Or do you require them for wood bottom plates as well?

Note that for some preservatives, a higher grade of galvanizing is required. And for others, stainless hardware is required.

1. They wont be painted properly (if at all).
2. they are much thinner than normal structural steel and therefore much more susceptable to corrosion.
Also agree with Jed regarding the influence of the pressure treatment.

Any connectors which are in contact with Preservative treated wood and exposed to moisture should have the Z-max coating which is G185. If you have a treated member in a dry environment, the standard G90 coating would be sufficient.
Note that I referred to dry and moist not interior and exterior. If the treated wood is near an indoor swimming pool, a damp crawl space or any process that may have a very humid environment the Z-max or stainless steel connectors should be used. Simpson has a chart near the front of their catalog (p. 11 in the 2010 catalog) for exposure environments with the different chemicals presently being used for treatment.

This must be what I was thinking of. So I assumed this should called for on all bottom plate connectors and any other connectors in contact with PT wood?
